Merino wool is a type of wool that is derived from the merino sheep. It is known for its softness, breathability, and moisture-wicking properties, and is often used in clothing and other textiles. While merino wool has many beneficial properties, it may not be the ideal material for saddle pads for a few reasons.
Merino wool is a relatively soft and fine type of wool, which can make it less durable and more prone to wear and tear than other types of wool. This can be a problem for saddle pads, which need to be able to withstand regular use and maintain their shape and support over time. In addition, the fine fibers of merino wool can also be more susceptible to snagging and pulling, which can cause the saddle pad to lose its shape and support.
While merino wool is breathable and moisture-wicking, it is not as effective at wicking moisture away from the horse's back as some other types of wool. This can be a problem in hot and humid conditions, where the horse's back can become sweaty and uncomfortable.
Other types of wool, such as wool from sheep breeds that have a thicker and more durable fibre are better suited for equestrian uses.
